Right now, you’re able to select the appropriate gender marker on your passport without a note from a medical professional (and a passport can be used in the vast majority of situations you’d use a birth certificate) but because the self select gender marker was done by executive action, it’s extremely likely to be reversed when Trump takes office.
Also, having one might be a good idea in general.
I’m rushing to get my name legally changed so my updated passport can be correct. My current one has 5 more years, but so it’s all my amab info. I’m terrified of how little time is left.
Another tip: A passport card is considered as valid as a passport book within the US, but it is much cheaper to obtain. It is conclusive proof of citizenship and an authoritative RealID-compliant identity card, just like a passport book. Passport cards are valid for land and sea travel within North America and the Caribbean. They’re not valid for international air travel (but they can be used for domestic flights).
Edit: Upgrading from a passport card to a passport book is considered a renewal rather than a new application. You can still keep the card if you later want to “renew” it for a book.
This sounds like exactly the type of thing they’ll reverse, either through executive action or pushing through the GOP Congress and Supreme Court. If you can afford it, go for the full US passport.
Honestly, I doubt they’d mess with the cards. They’re extremely common and useful for people who live in border states - Minnesota encourages them at our DMVs, and if you know about the northwest angle it’s likely a big part of why.
Wish I was privileged enough too :'(
